    Coastal Slope Stability Assessment

    Geoff Davis has recently been in his element, carrying a slope stability assessment for a holiday park that has recently seen some quite dramatic ground movements.One thing that this project has highlighted is that for all the new technologies that are available to help us understand the ground, including LiDAR, drone surveys, remote sensing and inclinometers, all of which we intend to use on this site, they are of little use if the ground model is not understood. And this understanding of geology and geomorphology only come from a combination of education and experience.It is hoped that our understanding of the landslide processes at this complex site will allow us to predict possible future behaviour and assist in developing a long-term strategy for the future of the holiday park and its management.

    Ground Investigation Report, Cornwall

    A Ground Investigation Report, fulfilling the requirements set out in BS EN 1997-2: Ground Investigation & Testing, was produced for an extension to a school in Dorset. The Ground Investigation Report (GIR) presented a factual record of the ground and groundwater conditions encountered, together with the laboratory testingresults, followed by a review of the ground profile and geotechnical parameters for foundation design. The Ground Investigation Report was issued promptly, shortly after the receipt of the laboratory testing results, less than three weeks after the completion of siteworks. Interim parameters for design were provided prior to the receipt of the laboratory testing results, based on field observations and in-situ testing results.

    Pre-Purchase Phase 1 Contamination Assessment

    Phase 1 Contaminated Land Assessment for the proposed redevelopment of a brownfield site in Devon, as part of the pre-purchase appraisal for the construction of a new supermarket. The site had numerous historical industrial land uses, including an iron foundry, gas works and an engineering works, as well as documented evidence of historical contamination of the ground, associated with an adjacent gas works. The production of the Phase 1 was crucial to understanding the potential development (and cost) constraints at this site for the client, prior to purchasing, and formed the basis of the scope of works for the Phase 2 Contamination Investigation.
